' This invention relates to oonveyers and the like for conveying material from one level to another.

Another object of the invention contemplates the provision and arrangement of agitators for the conveyor apparatus to keep the material in motion.

An additional object of the invention consists of an operating mechanism for the agitators.

More specifically stated the agitators are connected with the operating mechanism in such manner that the material will be allowed to pass beneath the agitators between strokes whereby continuity of flow will be facilitated.

With the above and other objects in view, the invention further consists of the following novel features and details of construc- 0 tion, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings t Figure l is a fragmentary longitudinal sectional view taken through a trough or sluice showing the present invention as applied for use.

Figure 2 is a fragmentary side elevation of the operating mechanism.

Figure 3 is a longitudinal sectional view taken online 3-3 of Figure 2. i

Figure 4 is a horizontal sectional view taken on line 4% of Figure 2. F igure 5 is a sectional view taken through one of the connections and mounted for the agitators upon the operating mechanism.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character indicates generallyone side wall of a form of support having a connecting upper wall 11; the initial side wall having a shaft 12 extended therethrough. A pulley wheel 13,

mounted upon the outermost end of the shaft .45"; 12, is driven by a motor 14: through the employment of an endless belt 15.

An elongated plate, such as indicated at 16, having an annular wall 17 upon one side thereof round at its ends and extending in 5: parallelism atits sides with the adjacent side edges of the plate 16 proper. A block 18, disposed upon one side of the plate 16 and within the confines of the flange 17, terminates toprovide rounded extremities 19 in spaced relation to the curved ends of said annulus. Bolt members 20 passed through the immediate portions of the plate 16 and block 18 also support sleeve members 21 and a retaining plate 22 common to all of the bolt members to prevent displacement of the w sleeve members 21. The ends of the retain ing plate 22 extends for appreciable distances outwardly and beyond the sleeves 21 and in conjunction with the block 19 provides a raceway 23 within which the teeth 24 of a sprocket gear 25 may be guided for engagement with the sleeves 21. The raceway 26 formed between the adjacent sides of the annulus 17 and the block 18 is provided for a sleeve bearing 27 carried upon a reduced portion 7 28 of the shaft 12 and by means of which the teeth of the sprocket gear 25 will be aligned for registration with the sleeves 21.

A line shaft generally designated as at L and composed of multiple pipe sections having series of universal joint couplings there between is designed for reciprocating action with the plate 16 in the following manner.

Attaching plates 29, carried upon opposite sides of the plate member 16 in the manner shown in Figure 3 of the drawings are curved, as at 30, upon their opposite ends and apertured to accommodate the projecting pintles or trunnions of a saddle plate having engagement with the upper surface and immediate section of the line shaft. A U-bolt arranged upon the aforementioned section of the line shaft has the uppermost projecting ends thereof passed through the saddle plate and nuts or other fastening devices secured thereon whereby the plate 16 and line shaft L will reciprocate in unison. This especial form of connection is adequately illustrated in Figure 5 of the drawings although same is particularly applicable to the agitators about to be described. Said agitators, indicated asat 31, having attaching arms 32 upon opposite sides thereof have their opposite ends upwardly curved and apertured to accommodate the pintles or trunnions 33 of saddle plates 34 having en-' gagement with the under surfaces of the sec-,

tions of the line shaft L. U-bolts 35 disposed in the manner shown in Figure 5 of the drawings have the depending extremities thereof passed through appropriate portions of the saddle plates 34 and subsequently receive nuts or other fastenings 36 to prevent displacement of the agitator connections with the line shaft.

By this arrangement the agitators induce only their exact weight against the coal or other material passing through the sluice or trough and in the instance of dispensing or delivering coal in lump form therethrough, it is to be noted that the lumps will not be unduly broken or converted into another grade of coal. As the shaft 12 rotates continuously in one direction, it is to be noted that the plate 16 will oscillate with relation thereto incident to the travelling of the sprocket wheel 25 upon opposite sides of the retaining plate 22 and engaging the sleeves 21. The coal or other material travelling through, the sluiceor trough will be prevented from clogging incident to the shoving action of the agitators about to be delivered thereby from the exact position of the invention in Figure 1 of the drawings.

As an instance of-the application of the present invention, it may be stated that the uppermost inclined end of the trough or sluice may be disposed adjacent the working surface or breast of the vein.

7 The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes'as prop-' erly fall within the scope of the appended claims.
